Check engine light problem

I have a check engine light on in my 84 trans am, i did the whole paper clip thing and i still cannot get it to flash out the codes for me! If its defective is there any other way to pull the codes?

Re: Check engine light problem

Alright heres what ive got, I just got a 84 trans am Recaro edition, it has the VIN code G L69 305 HO engine, all original , I got the car for free, it has been sitting for a while, i rebuilt the Quadra Jet, and the car was running good besides the exhaust leak annoying the crap outta me. I was driving it the other night and out of no where the check engine light popped on and it started running like a dog.I got home a noticed two wires were burnt on the exhaust, I fixed them, I tried to do the self test and can not get the check engine light to blink the codes off to me, then i hooked a dwell meter on to make sure i didnt have to readjust the mixture solenoid again and now im getting nothing on the dwell, is it possible the ecm just went out on it? Im new to GM's
